Morphological assessment of Co2-laser fusion using a flexible light guide in lymphovenous and venovenous anastomoses in experimental animals

In experiments on 13 mongrel dogs with CO2 laser supplied with flexible fiber guide there were formed 17 lympho-venous and 4 veno-venous anastomosis. There were no inadequate sealing, narrowing or aneurysm of the anastomosis. Histopathologic investigations after 3, 6-8, 13-16 days and 1 year showed that vascular walls were positioned correctly. Endothelial surface has continuous character both along the vessel as anastomosis line.
